Increasing quality of service using swarm intelligence technique through bandwidth reservation scheme in 4G mobile communication Systems
Kershinee Reddy, S. Varadarajan · 2011
In this paper, two self-adaptive bandwidth reservation schemes, which adopt support vector regression and swarm intelligence techniques, respectively, are proposed to reduce the forced termination probability of multimedia handoffs. Meanwhile, a proportional differentiated service model is incorporated into our schemes to accommodate new metrics used in processing handoffs in next generation networks. The simulation results show that both the proposed schemes can achieve superior performance than the representative band-width-reserving schemes in the literature when performance metrics are measured in terms of the forced termination probability for the handoffs, the call blocking probability for the new connections and bandwidth utilization.
